ogre-assimp - No codecs registered Topic is solved

[JanKleemann]

Ogre Version: 1.10.12
Operating System: Windows 10
Render System: -

Hi, I'm trying to convert some models using ogre-assimp, but I always get the message

Code: Select all

There are no formats supported (no codecs registered).

I have build FreeImage as described in http://wiki.ogre3d.org/Building+Dependencies (changed runtime libraries to DLL). I have build the tests for FreeImage and they run fine. I have build and run the tests for Ogre (TestContext.exe) and loading images seem to run fine (D3D11), although the test wants to access some images in C:\Users\kleemann\Documents\Ogre\Xalafu\VisualTests\VTests\Direct3D11RenderingSubsystem which don't exist (the folder is empty).

I have copied OgreAssimpConverter.exe, FreeImage.dll and assimp-vc140-mt.dll into the Ogre bin folder.

Does anyone have a clue why ogre-assimp won't load images?
Is there any other method to convert models into ogre .mesh? I have tried the blender plugin, but it does not work for me.

Below is the output from CMake, when configuring Ogre.

Likely a bug in ogre-assimp

[JanKleemann]

I added the line

Code: Select all

Ogre::FreeImageCodec::startup();

to main.cpp in ogre-assimp and included the corresponding header. After this the conversion works.

If this is intended behavior (Ogre not registering codecs by itself), then it is really a bug in ogre-assimp.

just pushed a fix to ogre-assimp. It never should have tried to load the image in the first place as it was not doing anything with them. Also the code is compatible with 1.11 now.
